这个简短的说明增加了早期的尝试，在识别晚更新世/早全新世在近东地区的网站耕地杂草。十九个潜在的耕地杂草类群，没有已知的用途被选中。这些分类群的发生在形态野生谷物的网站进行了比较，形态国内谷物的网站。假定的耕地杂草类群是常见的三个PPNA（前陶器新石器时代A）网站没有驯化，因为他们是在中东PPNB（前陶器新石器时代B）网站驯化，这有助于支持前国内种植在前网站的论点。可耕地杂草类群在纳图夫遗址中不太常见，但它们的存在引发了一个问题，即它们是否起源于耕地，或者是在自然栖息地偶然与野生谷物一起收集的杂草的祖先。
This short note adds to earlier attempts at identifying arable weeds on late Pleistocene/early Holocene sites in the Near East. Nineteen potential arable weed taxa that have no known use were selected. The occurrence of these taxa at sites with morphologically wild cereals was compared to sites with morphologically domestic cereals. The presumed arable weed taxa were as common on three PPNA (Pre Pottery Neolithic A) sites without domestication as they were on Middle PPNB (Pre Pottery Neolithic B) sites with domestication, which lends support to arguments for pre-domestic cultivation at the former sites. Arable weed taxa were less common at Natufian sites but their presence raises the question of whether they originated in cultivated fields or were the ancestors of weeds gathered accidentally alongside wild cereals in their natural habitat.
